To all 'whom it may concern Be it known that 1, CHRISTIAN EvENsEN, asubject of the King .of Norway, residing at Choteau, in the county ofTeton and State of Montana, have invented a new and use'- fulDoor-Catch, of which the following is a specification.

My invention is intended for use on doors of cabinets, cupboards, andthe like, and the Aobjects of my improvement are to provide a devicewhich will firmly secure a door by the simple act of pushing'it shut,and which will unfasten the door'by the simple `act of pulling outwardlyon the knob, thus making unnecessary 'either a twisting or a sidewisemotion on the knob before pulling outwardly.

A working parts inside.

A practical form of my invention as applied to a cupboard having doorsand shelves of wood, is illustrated in the accompanying drawing.However, the device is equally as Well adapted to cabinets, cases, etc.,made of metal.

Referring to the drawing: Figure 1 is a front view of a small portion ofthe two doors with knob and escutcheon in place. Fig. 2 is an insideView of the same small portion of the doors, with the shelf removed toVclearly show parts which attach to the doors. Fig. 3 is a View lookingupward, being partly insection, taken on the line m-w of Fig. 1, andshowing doors closed and catch holding. Fig. 4 is a View taken the sameas in Fig. 3, but showing doors unfastened and the right hand -oneslightly aj ar. Fig. 5 is an enlarged side view of the door-plate andplunger assembly, shown as detached from the door and viewed in thedirection indicated by the line y-y of Fig. 2. Fig. 6 is a sectionalside view taken on the line z-z of Fig. 4.

Similar indices refer to similar parts throughout the 'several views.The main body. of the door-plate 2 forms the inner guide for plunger'land has holes for 'attachment to door with screws or by other means. Inaddition, plate 2 has two bent projections, the hook c and the part d,which form the front guide for plunger l and act also as the frontl restfor push- 'spring 12. The rear end of spring 12 pushes 'against washer11 and pin 10, which latter Specification of Letters Patent.l

-is disposed through the plunger and projects 'a' 'little on eitherside. Spring 12 is quite light, belng just strong enough to retainplunger 1 at its inner limit, with pin 10 resting against the plate 2.The main part of plunger 1 is shown to be square, but the smaller partg, extending from the shoulder k forward, is round and has the forward.end threaded for attachment of knob 5.' Shoulder h, by striking againstthe rest d just as the inner end of l comes Hush with the inner surfaceof 2, serves as a limit to prevent pullig plungerl 1 too far. Theplunger assembly is shown as fitted to door 20. The escutcheon 6 servesonly as an ornament, and may be made in any suitable shape or artisticdesign.- Likewise the knob may be made in various designs. Theeyepiece-4 is attached to door 21.

The double-leg catch piece 3 is pivotedA (by rivet' 8) tothe central',circular, raised portion of the plate 7, which latter is attached tothe' under side of shelf 22. Plate 7 has also two projections, the lug ewhich serves 'as a stop to .limit the backward rotation of piece 3, andthe lug f, upon which one end of torsion springt) is hooked. This springis very light, and is disposed around the central raised portion'of 7,and has yits other end hooked over the edge of leg a.

Fig. 3 shows the doors fastened. The toe` of leg Z1 projects through theeye of piece4 and the toe of leg a is retained in hook c by means of theplunger 1.. Now, by simply pulling onknob 5, the plunger 1 first clearsthe heel of leg a, then the pull of the hook 0 Yon top of the toe arotates the piece 3 back out of engagement to the position shown in Fig.4. Spring 9 is just strong enough to retain 3 in this position wheneverthe doors are open.l It is obvious thatthe pull necessary to open thedoor .is utilized to unfasteny the catch, and that the need of either atwisting or a sidewise motion on the knob is eliminated.

' action is considerably to one side of the pivot point 8, causes thetoe .of a to move readily into hook c. and piece 3 to rotate about thepivot. During this movement of a in entering the hook c, plunger 1 isforced back against the action of springl 12, until the door closes andthe toe of a is clear back in be left olf. These parts are most neededin.v

those cases Where the door 20 does not overlap door 21. It is plain thatwhen used on a pair of doors, my invention 4takes the place of bothelbow-catch and cupboard-tu`rn or catch, and that the lnumber of motionsused in opening the doors is appreciably reduced.

I claim: Y

In a door catch, a foot-sha`ped arm, being pivoted at its inner end toshelf or case, and having its longitudinal center line disposed incenseclosed, the inner` end of the plunger strikes the arm near its outerend, the, aforesaid oblique disposal of the arm, together with theclosing movement of the door, causing the arm to engage the hook, inwhich engagement thearm and the hook are retained by the plunger, allsubstantially asvdescribed for the purpose specified.
